Exporting in IGES Format (3D only)

The Export IGES (3D only) command exports 3D curves, surfaces and solids from VectorWorks into IGES format (version 5.3). Closed solids are exported as solids, while open solids are exported as a collection of surfaces.

Objects that are exported to an .igs file from VectorWorks include:

 

3D loci	3D polygons	Chamfers
CSG solids (add/subtract/intersect/section)	Extrudes and multiple extrudes	Fillets
Groups	NURBS curves and surfaces	Parametric objects
Shells	Solids (sphere/cone/hemisphere)	Sweeps
Symbols

To export a file to the IGES format:

1.	Select File > Export > Export IGES (3D only).

The Export Options dialog box opens.

2.	Select Export Solid as Trimmed Surfaces to export a solid as several different “bodies” (for example, a cube exports as six bodies); otherwise, a solid is exported as a single body.

3.

Click OK.

4.	Specify the file name and destination.

5.	Click Save.

 

Export Item	Export Result

Trimmed NURBS surface	IGES Entity Type 144
Closed solid	IGES Entity Type 186
